Artificial reality notification triggers

ABSTRACT

An artificial reality system can display notifications in various configurations including in a minimized version or a maximized version. The artificial reality system can initially display a minimized version of the notification. Upon identifying a first trigger event, such as the user&#39;s gaze resting on the minimized version of the notification or a rotation of a user&#39;s wrist, the artificial reality system can change the display of the notification from the minimized version to the maximized version. The artificial reality system can identify a second trigger event, such as the user&#39;s gaze not being directed to the maximized version of the notification or a rotation of the wrist in an opposite direction from the first wrist rotation. In response to the second trigger event, the artificial reality system can stop display of the maximized version of the notification.

TECHNICAL FIELD

The present disclosure is directed to interactions and notifications inan artificial reality environment.

BACKGROUND

Various objects in an artificial reality environment are “virtualobjects,” i.e., representations of objects generated by a computingsystem that appear in the environment. Virtual objects in an artificialreality environment can be presented to a user by a head-mounteddisplay, a mobile device, a projection system, or another computingsystem. Some virtual objects can be notifications, such as systemnotifications, communication notifications, alarms, notifications fromrunning applications, notifications from remote sources, etc. Existingartificial reality systems tend to display notifications over the middleof the display area or in a corner, regardless of the user's actions.

DETAILED DESCRIPTION

Embodiments for displaying notifications configured according to triggerevents in an artificial reality environment are described herein. Anartificial reality system can display notifications in variousconfigurations including in a minimized version or a maximized version.A minimized version configuration, for example, can include media and/orparameters such as an icon or other symbol, a textual summary, aspecified minimized size, an inconspicuous display location, etc. Amaximized version configuration, for example, can include fullnotification text, images, animation or video, a specified maximizedsize, etc. In some implementations, notification configurations can alsoinclude other output characteristics for the notifications, such asnotification sounds or haptics, notification colors, fonts, patterns,sizes, or border properties, etc. In some implementations, notificationconfigurations can also specify how a notification interacts with otherreal or virtual objects, such as which object the notification isattached to, whether the notification is placed in front of or behindobjects in virtual space, whether the notification moves in relation touser movement, whether the notification reacts to other objects (e.g.,whether the notification can be moved aside in reaction to other objectsor whether the notification can move aside other objects), etc.

In some implementations, the artificial reality system can receive anindication of a notification that is associated with notificationconfigurations for both a minimized version and maximized version of thenotification. The artificial reality system can initially display aminimized version of the notification, e.g., at a designated location inthe artificial reality environment, at a location relative to the user'sviewpoint such as in the corner of the display area, or attached to avirtual object such as a representation of the user's wrist in theartificial reality environment. The artificial reality system can thenidentify a first trigger event, such as the user's gaze resting on theminimized version of the notification for a threshold amount of time or,when the minimized version of the notification is attached to the backof the user's virtual wrist, a rotation of the wrist by a thresholdamount. In response to the first trigger event, the artificial realitysystem can change the display of the notification from the minimizedversion to the maximized version. In some implementations, the minimizedversion and/or the maximized version are displayed for a set amount oftime. Alternatively, the artificial reality system can identify a secondtrigger event, such as the user's gaze not being directed to themaximized version of the notification for a threshold amount of time ora rotation of the wrist in an opposite direction from the first wristrotation by a threshold amount. In response to the second trigger event,the artificial reality system can stop display of the maximized versionof the notification. This can include re-displaying the minimizedversion or no longer displaying a version of the notification.

In some implementations, the notification configurations used fordisplaying a notification can be based on a mapping of notificationtypes to notification configurations. In various implementations, thismapping can be for the notification generally, for the minimized versionof the notification, or for the maximized version of the notification.In some implementations, the artificial reality system can identify atype for the notification based on a type indicator associated with thenotification. In some implementations, the artificial reality system canuse a second mapping of an identified notification context tonotification types. Examples of combinations of notification contextsthat can be mapped to types include an identification of an applicationor operating system that was a source of the pending notification, anidentification of an organization that was the source of pendingnotification, an identification of a relationship between a current userand a user associated with the pending notification, an identificationof a subject of the pending notification, an identification of a systemresource to which the notification relates, etc. The artificial realitysystem can then use the first mapping to select notificationconfigurations associated with the identified type and display thenotification with the selected notification configurations.

Embodiments of the disclosed technology may include or be implemented inconjunction with an artificial reality system. Artificial reality orextra reality (XR) is a form of reality that has been adjusted in somemanner before presentation to a user, which may include, e.g., a virtualreality (VR), an augmented reality (AR), a mixed reality (MR), a hybridreality, or some combination and/or derivatives thereof. Artificialreality content may include completely generated content or generatedcontent combined with captured content (e.g., real-world photographs).The artificial reality content may include video, audio, hapticfeedback, or some combination thereof, any of which may be presented ina single channel or in multiple channels (such as stereo video thatproduces a three-dimensional effect to the viewer). Additionally, insome embodiments, artificial reality may be associated withapplications, products, accessories, services, or some combinationthereof, that are, e.g., used to create content in an artificial realityand/or used in (e.g., perform activities in) an artificial reality. Theartificial reality system that provides the artificial reality contentmay be implemented on various platforms, including a head-mounteddisplay (HMD) connected to a host computer system, a standalone HMD, amobile device or computing system, a “cave” environment or otherprojection system, or any other hardware platform capable of providingartificial reality content to one or more viewers.

“Virtual reality” or “VR,” as used herein, refers to an immersiveexperience where a user's visual input is controlled by a computingsystem. “Augmented reality” or “AR” refers to systems where a user viewsimages of the real world after they have passed through a computingsystem. For example, a tablet with a camera on the back can captureimages of the real world and then display the images on the screen onthe opposite side of the tablet from the camera. The tablet can processand adjust or “augment” the images as they pass through the system, suchas by adding virtual objects. “Mixed reality” or “MR” refers to systemswhere light entering a user's eye is partially generated by a computingsystem and partially composes light reflected off objects in the realworld. For example, a MR headset could be shaped as a pair of glasseswith a pass-through display, which allows light from the real world topass through a waveguide that simultaneously emits light from aprojector in the MR headset, allowing the MR headset to present virtualobjects intermixed with the real objects the user can see. “Artificialreality,” “extra reality,” or “XR,” as used herein, refers to any of VR,AR, MR, or any combination or hybrid thereof.

There are existing artificial reality systems that displaynotifications. However, the notifications provided by these existingartificial reality systems are often intrusive or fail to providesufficient information about a notification. This makes existingartificial reality systems frustrating and difficult to operate. Thenotification configuration triggering system and processes forartificial reality environments described herein are expected toovercome these problems of existing artificial reality systems and areexpected to provide users with greater control over notificationinteractions, offer more functionality, and decrease likelihood ofnotifications being an unwelcome intrusion upon the user's artificialreality experience. The notification configuration triggering system andprocesses described herein are rooted in computerized artificial realityand user tracking systems, instead of being an analog of traditionalintra-personal interactions. For example, existing interactiontechniques fail to provide a method specific to artificial reality(e.g., based on body tracking) for setting and changing notificationconfigurations.

Several implementations are discussed below in more detail in referenceto the figures. FIG. 1 is a block diagram illustrating an overview ofdevices on which some implementations of the disclosed technology canoperate. The devices can comprise hardware components of a computingsystem 100 that configures notifications based on user activatedtriggers, such as gaze tracking or monitored wrist movements. In variousimplementations, computing system 100 can include a single computingdevice 103 or multiple computing devices (e.g., computing device 101,computing device 102, and computing device 103) that communicate overwired or wireless channels to distribute processing and share inputdata. In some implementations, computing system 100 can include astand-alone headset capable of providing a computer created or augmentedexperience for a user without the need for external processing orsensors. In other implementations, computing system 100 can includemultiple computing devices such as a headset and a core processingcomponent (such as a console, mobile device, or server system) wheresome processing operations are performed on the headset and others areoffloaded to the core processing component. Example headsets aredescribed below in relation to FIGS. 2A and 2B. In some implementations,position and environment data can be gathered only by sensorsincorporated in the headset device, while in other implementations oneor more of the non-headset computing devices can include sensorcomponents that can track environment or position data.

Computing system 100 can include one or more processor(s) 110 (e.g.,central processing units (CPUs), graphical processing units (GPUs),holographic processing units (HPUs), etc.) Processors 110 can be asingle processing unit or multiple processing units in a device ordistributed across multiple devices (e.g., distributed across two ormore of computing devices 101-103).

Computing system 100 can include one or more input devices 120 thatprovide input to the processors 110, notifying them of actions. Theactions can be mediated by a hardware controller that interprets thesignals received from the input device and communicates the informationto the processors 110 using a communication protocol. Each input device120 can include, for example, a mouse, a keyboard, a touchscreen, atouchpad, a wearable input device (e.g., a haptics glove, a bracelet, aring, an earring, a necklace, a watch, etc.), a camera (or otherlight-based input device, e.g., an infrared sensor), a microphone, orother user input devices.

Processors 110 can be coupled to other hardware devices, for example,with the use of an internal or external bus, such as a PCI bus, SCSIbus, or wireless connection. The processors 110 can communicate with ahardware controller for devices, such as for a display 130. Display 130can be used to display text and graphics. In some implementations,display 130 includes the input device as part of the display, such aswhen the input device is a touchscreen or is equipped with an eyedirection monitoring system. In some implementations, the display isseparate from the input device. Examples of display devices are: an LCDdisplay screen, an LED display screen, a projected, holographic, oraugmented reality display (such as a heads-up display device or ahead-mounted device), and so on. Other I/O devices 140 can also becoupled to the processor, such as a network chip or card, video chip orcard, audio chip or card, USB, firewire or other external device,camera, printer, speakers, CD-ROM drive, DVD drive, disk drive, etc.

Computing system 100 can include a communication device capable ofcommunicating wirelessly or wire-based with other local computingdevices or a network node. The communication device can communicate withanother device or a server through a network using, for example, TCP/IPprotocols. Computing system 100 can utilize the communication device todistribute operations across multiple network devices.

The processors 110 can have access to a memory 150, which can becontained on one of the computing devices of computing system 100 or canbe distributed across of the multiple computing devices of computingsystem 100 or other external devices. A memory includes one or morehardware devices for volatile or non-volatile storage, and can includeboth read-only and writable memory. For example, a memory can includeone or more of random access memory (RAM), various caches, CPUregisters, read-only memory (ROM), and writable non-volatile memory,such as flash memory, hard drives, floppy disks, CDs, DVDs, magneticstorage devices, tape drives, and so forth. A memory is not apropagating signal divorced from underlying hardware; a memory is thusnon-transitory. Memory 150 can include program memory 160 that storesprograms and software, such as an operating system 162, artificialreality (XR) notification configuration triggering system 164, and otherapplication programs 166. Memory 150 can also include data memory 170that can include, for example, notification content, triggerdefinitions, notification configurations, mappings of notificationcontext to notification types, mappings of notification types tonotification configurations, settings, user options or preferences,etc., which can be provided to the program memory 160 or any element ofthe computing system 100.

Some implementations can be operational with numerous other computingsystem environments or configurations. Examples of computing systems,environments, and/or configurations that may be suitable for use withthe technology include, but are not limited to, XR headsets, personalcomputers, server computers, handheld or laptop devices, cellulartelephones, wearable electronics, gaming consoles, tablet devices,multiprocessor systems, microprocessor-based systems, set-top boxes,programmable consumer electronics, network PCs, minicomputers, mainframecomputers, distributed computing environments that include any of theabove systems or devices, or the like.

FIG. 2A is a wire diagram of a virtual reality head-mounted display(HMD) 200, in accordance with some embodiments. The HMD 200 includes afront rigid body 205 and a band 210. The front rigid body 205 includesone or more electronic display elements of an electronic display 245, aninertial motion unit (IMU) 215, one or more position sensors 220,locators 225, and one or more compute units 230. The position sensors220, the IMU 215, and compute units 230 may be internal to the HMD 200and may not be visible to the user. In various implementations, the IMU215, position sensors 220, and locators 225 can track movement andlocation of the HMD 200 in the real world and in a virtual environmentin three degrees of freedom (3DoF) or six degrees of freedom (6DoF). Forexample, the locators 225 can emit infrared light beams which createlight points on real objects around the HMD 200. One or more cameras(not shown) integrated with the HMD 200 can detect the light points.Compute units 230 in the HMD 200 can use the detected light points toextrapolate position and movement of the HMD 200 as well as to identifythe shape and position of the real objects surrounding the HMD 200.

The electronic display 245 can be integrated with the front rigid body205 and can provide image light to a user as dictated by the computeunits 230. In various embodiments, the electronic display 245 can be asingle electronic display or multiple electronic displays (e.g., adisplay for each user eye). Examples of the electronic display 245include: a liquid crystal display (LCD), an organic light-emitting diode(OLED) display, an active-matrix organic light-emitting diode display(AMOLED), a display including one or more quantum dot light-emittingdiode (QOLED) sub-pixels, a projector unit (e.g., microLED, LASER,etc.), some other display, or some combination thereof.

In some implementations, the HMD 200 can be coupled to a core processingcomponent such as a personal computer (PC) (not shown) and/or one ormore external sensors (not shown). The external sensors can monitor theHMD 200 (e.g., via light emitted from the HMD 200) which the PC can use,in combination with output from the IMU 215 and position sensors 220, todetermine the location and movement of the HMD 200.

In some implementations, the HMD 200 can be in communication with one ormore other external devices, such as controllers (not shown) which auser can hold in one or both hands. The controllers can have their ownIMU units, position sensors, and/or can emit further light points. TheHMD 200 or external sensors can track these controller light points. Thecompute units 230 in the HMD 200 or the core processing component canuse this tracking, in combination with IMU and position output, tomonitor hand positions and motions of the user. The controllers can alsoinclude various buttons a user can actuate to provide input and interactwith virtual objects. In various implementations, the HMD 200 can alsoinclude additional subsystems, such as an eye tracking unit, an audiosystem, various network components, etc. In some implementations,instead of or in addition to controllers, one or more cameras includedin the HMD 200 or external to it can monitor the positions and poses ofthe user's hands to determine gestures and other hand and body motions.

FIG. 2B is a wire diagram of a mixed reality HMD system 250 whichincludes a mixed reality HMD 252 and a core processing component 254.The mixed reality HMD 252 and the core processing component 254 cancommunicate via a wireless connection (e.g., a 60 GHz link) as indicatedby link 256. In other implementations, the mixed reality system 250includes a headset only, without an external compute device or includesother wired or wireless connections between the mixed reality HMD 252and the core processing component 254. The mixed reality HMD 252includes a pass-through display 258 and a frame 260. The frame 260 canhouse various electronic components (not shown) such as light projectors(e.g., LASERs, LEDs, etc.), cameras, eye-tracking sensors, MEMScomponents, networking components, etc.

The projectors can be coupled to the pass-through display 258, e.g., viaoptical elements, to display media to a user. The optical elements caninclude one or more waveguide assemblies, reflectors, lenses, mirrors,collimators, gratings, etc., for directing light from the projectors toa user's eye. Image data can be transmitted from the core processingcomponent 254 via link 256 to HMD 252. Controllers in the HMD 252 canconvert the image data into light pulses from the projectors, which canbe transmitted via the optical elements as output light to the user'seye. The output light can mix with light that passes through the display258, allowing the output light to present virtual objects that appear asif they exist in the real world.

Similarly to the HMD 200, the HMD system 250 can also include motion andposition tracking units, cameras, light sources, etc., which allow theHMD system 250 to, e.g., track itself in 3DoF or 6DoF, track portions ofthe user (e.g., hands, feet, head, or other body parts), map virtualobjects to appear as stationary as the HMD 252 moves, and have virtualobjects react to gestures and other real-world objects.

FIG. 3 is a block diagram illustrating an overview of an environment 300in which some implementations of the disclosed technology can operate.Environment 300 can include one or more client computing devices 305A-D,examples of which can include computing system 100. In someimplementations, some of the client computing devices (e.g., clientcomputing device 305B) can be the HMD 200 or the HMD system 250. Clientcomputing devices 305 can operate in a networked environment usinglogical connections through network 330 to one or more remote computers,such as a server computing device.

In some implementations, server 310 can be an edge server which receivesclient requests and coordinates fulfillment of those requests throughother servers, such as servers 320A-C. Server computing devices 310 and320 can comprise computing systems, such as computing system 100. Thougheach server computing device 310 and 320 is displayed logically as asingle server, server computing devices can each be a distributedcomputing environment encompassing multiple computing devices located atthe same or at geographically disparate physical locations.

Client computing devices 305 and server computing devices 310 and 320can each act as a server or client to other server/client device(s).Server 310 can connect to a database 315. Servers 320A-C can eachconnect to a corresponding database 325A-C. As discussed above, eachserver 310 or 320 can correspond to a group of servers, and each ofthese servers can share a database or can have their own database.Though databases 315 and 325 are displayed logically as single units,databases 315 and 325 can each be a distributed computing environmentencompassing multiple computing devices, can be located within theircorresponding server, or can be located at the same or at geographicallydisparate physical locations.

Network 330 can be a local area network (LAN), a wide area network(WAN), a mesh network, a hybrid network, or other wired or wirelessnetworks. Network 330 may be the Internet or some other public orprivate network. Client computing devices 305 can be connected tonetwork 330 through a network interface, such as by wired or wirelesscommunication. While the connections between server 310 and servers 320are shown as separate connections, these connections can be any kind oflocal, wide area, wired, or wireless network, including network 330 or aseparate public or private network.

In some implementations, servers 310 and 320 can be used as part of asocial network. The social network can maintain a social graph andperform various actions based on the social graph. A social graph caninclude a set of nodes (representing social networking system objects,also known as social objects) interconnected by edges (representinginteractions, activity, or relatedness). A social networking systemobject can be a social networking system user, nonperson entity, contentitem, group, social networking system page, location, application,subject, concept representation or other social networking systemobject, e.g., a movie, a band, a book, etc. “Media” or “content items”can be any digital data such as text, images, audio, video, links,webpages, minutia (e.g., indicia provided from a client device such asemotion indicators, status text snippets, location indictors, etc.), orother multi-media. In various implementations, content items can besocial network items or parts of social network items, such as posts,likes, mentions, news items, events, shares, comments, messages, othernotifications, etc. Subjects and concepts, in the context of a socialgraph, comprise nodes that represent any person, place, thing, or idea.

A social networking system can enable a user to enter and displayinformation related to the user's interests, age/date of birth, location(e.g., longitude/latitude, country, region, city, etc.), educationinformation, life stage, relationship status, name, a model of devicestypically used, languages identified as ones the user is facile with,occupation, contact information, or other demographic or biographicalinformation in the user's profile. Any such information can berepresented, in various implementations, by a node or edge between nodesin the social graph. A social networking system can enable a user toupload or create pictures, videos, documents, songs, or other contentitems, and can enable a user to create and schedule events. Contentitems can be represented, in various implementations, by a node or edgebetween nodes in the social graph.

A social networking system can enable a user to perform uploads orcreate content items, interact with content items or other users,express an interest or opinion, or perform other actions. A socialnetworking system can provide various means to interact with non-userobjects within the social networking system. Actions can be represented,in various implementations, by a node or edge between nodes in thesocial graph. For example, a user can form or join groups, or become afan of a page or entity within the social networking system. Inaddition, a user can create, download, view, upload, link to, tag, edit,or play a social networking system object. A user can interact withsocial networking system objects outside of the context of the socialnetworking system. For example, an article on a news web site might havea “like” button that users can click or an object in an artificialreality environment can correspond to social network system object. Ineach of these instances, the interaction between the user and the objectcan be represented by an edge in the social graph connecting the node ofthe user to the node of the object. Such interactions can also triggernotifications for an associated other user or other users associatedwith the target object.

A social networking system can provide a variety of communicationchannels to users. For example, a social networking system can enable auser to email, instant message, or text/SMS message, one or more otherusers. It can enable a user to post a message to the user's wall orprofile or another user's wall or profile. It can enable a user to posta message to a group or a fan page. It can enable a user to comment onan image, wall post or other content item created or uploaded by theuser or another user. And it can allow users to interact (via theirpersonalized avatar) with objects or other avatars in a virtualenvironment, etc. In some embodiments, a user can invite another user toplay or watch a game, post a status message to the user's profileindicating a current event, state of mind, thought, feeling, activity,or any other present-time relevant communication. A social networkingsystem can enable users to communicate both within, and external to, thesocial networking system. For example, a first user can send a seconduser a message within the social networking system, send an emailthrough the social networking system, send an email external to butoriginating from the social networking system, send an instant messagewithin the social networking system, send an instant message external tobut originating from the social networking system, send voice or videomessaging, or interact in a virtual environment were users cancommunicate and interact via avatars or other digital representations ofthemselves. In various implementations, an artificial reality system canreceive notifications of these communication events and provide versionsof them to a user in the artificial reality environment.

Social networking systems enable users to associate themselves andestablish connections with other users of the social networking system.When two users (e.g., social graph nodes) explicitly establish a socialconnection in the social networking system, they become “friends” (or,“connections”) within the context of the social networking system. Forexample, a friend request from a “John Doe” to a “Jane Smith,” which isaccepted by “Jane Smith,” is a social connection. The social connectioncan be an edge in the social graph. Being friends or being within athreshold number of friend edges on the social graph can allow usersaccess to more information about each other than would otherwise beavailable to unconnected users. For example, being friends can allow auser to view another user's profile, to see another user's friends, orto view pictures of another user. Likewise, becoming friends within asocial networking system can allow a user greater access to communicatewith another user, e.g., by email (internal and external to the socialnetworking system), instant message, text message, phone, or any othercommunicative interface. Actions by a user can initiate a notificationto the friends of that user. Establishing connections, accessing userinformation, communicating, and interacting within the context of thesocial networking system can be represented by an edge between the nodesrepresenting two social networking system users.

FIG. 4 is a block diagram illustrating components 400 which, in someimplementations, can be used in a system employing the disclosedtechnology. Components 400 can be included in one device of computingsystem 100 or can be distributed across multiple of the devices ofcomputing system 100. The components 400 include hardware 410, mediator420, and specialized components 430. As discussed above, a systemimplementing the disclosed technology can use various hardware includingprocessing units 412, working memory 414, input and output devices 416(e.g., cameras, displays, IMU units, network connections, etc.), andstorage memory 418. In various implementations, storage memory 418 canbe one or more of: local devices, interfaces to remote storage devices,or combinations thereof. For example, storage memory 418 can be one ormore hard drives or flash drives accessible through a system bus or canbe a cloud storage provider (such as in storage 315 or 325) or othernetwork storage accessible via one or more communications networks. Invarious implementations, components 400 can be implemented in a clientcomputing device such as client computing devices 305 or on a servercomputing device, such as server computing device 310 or 320.

Mediator 420 can include components which mediate resources betweenhardware 410 and specialized components 430. For example, mediator 420can include an operating system, services, drivers, a basic input outputsystem (BIOS), controller circuits, or other hardware or softwaresystems.

Specialized components 430 can include software or hardware configuredto perform operations for displaying notifications in response totriggers associated with notification configurations. Specializedcomponents 430 can include user monitor 434, trigger event monitor 436,notification configuration mappings 438, notification display engine440, and components and APIs which can be used for providing userinterfaces, transferring data, accessing hardware, and controlling thespecialized components, such as interfaces 432. In some implementations,components 400 can be in a computing system that is distributed acrossmultiple computing devices or can be an interface to a server-basedapplication executing one or more of specialized components 430.

User monitor 434 can track various body parts of the user such as awrist location and rotation, an eye position and extrapolated gazedirection, hand or finger positions and directions, head positions andorientations, etc. In some implementations, user monitor 434 canaccomplish this by receiving camera and/or sensor data. For example, theuser monitor 434 can receive images from one or more cameras mounted onan artificial realty system headset, artificial realty systemcontrollers, external sensors, etc. and can identify body positionsdepicted in the images, e.g., using machine learning models. In somecases, body position information can also, or instead, be identifiedbased on inertial motion and/or position sensor data. In someimplementations, the body position data can be determined by applyingcamera and/or sensor data to a kinematic model of the user's body, amodel of the user's eye, etc.

Trigger event monitor 436 can receive data from user monitor 434 onpositions and orientations of user body parts and/or from interfaces 432providing indications of pending notifications and notification versionpositions in the artificial reality. Trigger event monitor 436 can usethis data to determine if the body positions and notification locationsmap to a trigger event for a notification. In various implementations,trigger event monitor 436 can identify a trigger event when a minimizedversion of a notification is attached to a user body part (such as awrist, forearm, or back of hand) and the body part or an inferred usercondition (e.g., the user's gaze) performs a particular action. Morespecifically, in one case, the trigger event monitor 436 can identify afirst trigger event when a user's wrist, with a minimized version of anotification attached to it, rotates a specified amount or rotates untila specified part of the wrist (e.g., opposite from the minimizednotification) is pointing at the user's face. Further, the trigger eventmonitor 436 can identify a second trigger event when the wrist isrotated a specified amount in an opposite direction or such that thepart of the wrist is no longer pointing toward the user's face. Inanother case, the trigger event monitor 436 can identify a first triggerevents when a user's gaze is directed at a minimized version of anotification for at least a first threshold amount of time and thetrigger event monitor 436 can identify a second trigger events when theuser's gaze is not on a maximized version of a notification for a secondthreshold amount of time.

Notification configuration mappings 438 can be mappings of notificationcontexts to how the notification is displayed. For example, when triggerevent monitor 436 has not identified a trigger action for anotification, that context can be mapped to display features showing aminimized version of the notification, such as only having an icon,having a maximum size, being at least partially transparent, etc. Asanother example, when trigger event monitor 436 has identified a triggeraction for a notification, that context can be mapped to showing alarger notification, displaying text from the notification, etc. As afurther example, when trigger event monitor 436 has identified a secondtrigger action for a notification, that context can be mapped to hidinga notification or returning to the minimized version of thenotification. Additional examples of notification contexts that can bemapped to notification display properties include an application oroperating system that was a source of the pending notification, anorganization that was the source of the pending notification, arelationship between a current user and a user associated with thepending notification, a subject of the pending notification, and/or asystem resource to which the notification relates. Additional examplesof display properties that notification contexts can be mapped toinclude one or more colors, one or more fonts, one or more borderproperties, how a notification interacts with other real or virtualobjects, and/or one or more patterns.

Notification display engine 440 can receive notifications via interfaces432 and can display them when triggered by trigger event monitor 436, ina format based on the notification configuration mappings 438 for acurrent context of the notification.

Those skilled in the art will appreciate that the components illustratedin FIGS. 1-4 described above, and in each of the flow diagrams discussedbelow, may be altered in a variety of ways. For example, the order ofthe logic may be rearranged, substeps may be performed in parallel,illustrated logic may be omitted, other logic may be included, etc. Insome implementations, one or more of the components described above canexecute one or more of the processes described below.

FIG. 5 is a flow diagram illustrating a process 500 used in someimplementations of the present technology for displaying notifications,in an artificial reality environment, configured according to triggerevents. In some implementations, process 500 can be executed by anartificial reality system (e.g., any of the systems described above) inresponse to a new notification, e.g., a notification generated by anoperating system of the artificial reality system, an applicationrunning on the artificial reality system, or by a remote system.

At block 502, process 500 can receive an indication of a pendingnotification. Examples of notifications include system notificationssuch as network connectivity notifications, resource controlnotifications (e.g., battery power, memory usage, processing usage,network usage, etc.), alarms, body tracking notifications, etc.Additional examples of notifications include application notifications,which can be any notification provided by an application in response toan event such as identifying particular input from a sensor, identifyinga particular configuration of objects in a virtual environment,identifying a particular time, receiving data from another application,operating system, or remote source, etc. Yet further examples ofnotifications include notifications from a remote source (which can besupplied into the artificial reality environment via the operatingsystem or an application), such as available update notifications,messaging notifications, or any other notification based on datareceived from a remote source.

At block 504, process 500 can display, in the artificial realityenvironment, a minimized version of the pending notification received atblock 502. In various implementations, the minimized version of thepending notification can be displayed at a particular location in theartificial reality environment, such as in the center of the user'sview, in a corner of the user's view, or attached to a control or menudisplayed in the artificial reality environment. In someimplementations, the minimized version of the notification can beattached to a particular object in the artificial reality environment,such as being positioned relative to an identified portion of a virtualrepresentation of the user's wrist (e.g., the back of the user's virtualwrist), another body part such as a forearm, fingertip, relative to theuser's face, or an external object such as an identified wall, tabletop, etc. In some implementations, the minimized version of thenotification can be initially positioned at a particular point in theartificial reality environment (e.g., half way up on the left side ofthe user's display), but can be world-locked to that display position inthe artificial reality environment. In some implementations, as the usermoves around in the artificial reality environment, the minimizedversion of the notification can move, at a set velocity, toward adesignated head-locked position, providing a “trailing” effect to theposition of the minimized version of the notification. In someimplementations, the minimized version of the notification can beinitially world-locked to a particular point in the artificial realityenvironment relative to the user. However, if the user moves or directsher gaze more than a threshold amount from that position, the artificialreality system can move the minimized version of the notification toreorient to the particular point relative to the new position of theuser, providing a “snapping” effect to the position of the minimizedversion of the notification.

In some implementations, the minimized version of the notification caninclude an image, icon, or symbol, without any text or with only alimited number of characters. In some cases, the minimized version ofthe notification can be shown as partially transparent, in muted orgrayed colors, with small or narrow font, etc. In some implementations,the minimized version of the notification can have a particular limitedsize. In some cases, the minimized version of the notification caninclude a summary or a preview of part of a maximized version of thenotification, e.g., a set number of the first characters from themaximized version of the notification, a part of an image from themaximized version of the notification, or a reduced size version of themaximized version of the notification. In some implementations,displaying the minimized version of the notification can include playingan associated sound or performing an associated haptic event (e.g., avibration). Examples of displaying a minimized version of a notificationare discussed below in relation to FIGS. 7A and 8A.

At block 506, process 500 can detect a first trigger event formaximizing a minimized notification. In some implementations, the firsttrigger event can be based on a tracked portion of at least part of auser. In some cases, this can be a tracked arm or wrist position. Forexample, where the minimized version of the notification is attached tothe back or front of a user's virtual wrist, the first trigger event canbe detecting a rotation of the wrist by a threshold amount or a wristrotation such that the other side of the wrist is pointing toward theuser's face. In some implementations, the tracked portion of the usercan be an eye position resulting in determining a user gaze direction.In this instance, the first trigger event can be determining that theuser's gaze is directed at the minimized version of the notification fora threshold amount of time. In some implementations, instead of a gazedirection, a trigger event can be based on another indicated directionfrom the user, e.g., pointing with another body part such as a hand orfinger or pointing with a hardware controller. Examples of detecting afirst trigger event are discussed below in relation to FIGS. 7B and 8B.

At block 508, in response to detecting the first trigger event at block506, process 500 can display a maximized version of the notification.Displaying the maximized version of the notification can include showingthe full text from the notification, or a larger threshold amount of thebeginning text from the notification than was shown in the minimizedversion of the notification. In some implementations, the maximizedversion of the notification can include a change in color, opacity,font, border style, etc., as compared to the minimized version of thenotification. In some cases, the maximized version of the notificationcan include an image, icon, or symbol from the minimized version of thenotification. In some implementations, the maximized version of thenotification can have a particular expanded size as compared to theminimized version. In some cases, the maximized version of thenotification can include an animation, video, 3D model, or other mediaor content item. Examples of displaying a maximized version of anotification are discussed below in relation to FIGS. 7B and 8C.

At block 510, process 500 can detect a second trigger event. In someimplementations, instead of performing blocks 510 and 512, process 500can end after block 508. When block 510 is performed, similarly to block506, the second trigger event can be based on a tracked portion of auser. In some cases, this can be a tracked arm or wrist position. Forexample, where the minimized version of the notification was attached tothe back or front of a user's virtual wrist, the second trigger eventcan be detecting a rotation of the wrist by a threshold amount in adirection opposite to the direction from the first trigger eventdetected at block 506. As another example, the second trigger event canbe a wrist rotation such that a side of the wrist with the maximizedversion of the notification is no longer pointing toward the user'sface. In some implementations, the tracked portion of the user can be aneye position resulting in determining a user gaze direction. In thisinstance, the second trigger event can be determining that the user'sgaze has not been directed at the maximized version of the notificationfor a threshold amount of time. In some implementations, instead of agaze direction, a trigger event can be based on another indicateddirection from the user, e.g., pointing with another body part such as ahand or finger or pointing with a hardware controller. Examples ofdetecting a second trigger event are discussed below in relation toFIGS. 7C and 8D.

At block 512, process 500 can, in response to the detected secondtrigger event at block 510, stop displaying the maximized version of thepending notification. For example, this can include hiding the maximizedversion of the pending notification or removing a data object for themaximized version of the pending notification from the artificialreality environment. In some implementations, the minimized version ofthe pending notification can be re-displayed. In other implementations,all indications of the notification can be hidden or removed. In somecases, an alternate control can be shown when the maximized version ofthe pending notification is no longer shown, such as a menu foraccessing past notifications or accessing system information. In someimplementations, a minimized or maximized version of a next pendingnotification can be displayed in response to the second trigger event.Examples of responding to a second trigger event are discussed below inrelation to FIGS. 7C and 8D. After block 512, process 500 can end, e.g.,until another indication of a notification is received.

FIG. 6 is a flow diagram illustrating a process 600 used in someimplementations of the present technology for selecting a notificationconfiguration according to a notification type. In some implementations,process 600 can be performed as a subprocess of process 500, e.g., atblock 504, block 508, and/or 512.

At block 602, process 600 can identify a type of a pending notification.In some implementations, identifying a notification type can includeidentifying a type indicator associated with the pending notification,e.g., set in the notification by the application or operating systemthat created the notification. In some implementations, identifying thenotification type is performed by using a mapping of an identifiednotification context to notification types. For example, notificationcontexts can include one or more of: an application or operating systemthat was a source of the pending notification; an organization that wasthe source of pending notification; a subject of the pendingnotification (e.g., automatically determined using natural languageprocessing and/or machine learning models); a system resource to whichthe notification relates; and/or a relationship between a current userand a user associated with the pending notification. Examples of suchrelationships include friends or friends-of-friends in a social network,a relationship through a current game or other application the user isrunning, a family relationship, a co-worker or employer relationship, acommon school or other organization, a common geographical area,previous communication history, or other connections identified throughconnections on a social graph.

At block 604, process 600 can access a mapping of notification types todisplay properties. Parts of this mapping can be set by the artificialreality system, by an individual application running on the artificialreality system, by the user, by a system administrator, by other users,etc. Examples of the display properties that notification types can bemapped to include one or more colors, one or more fonts, one or morepatterns, one or more border or margin properties, one or more images,icons, or videos to include in notification, one or more sounds to playwith the notification, one or more haptic responses to perform with thenotification, how the notification reacts to other virtual objects(e.g., overlapping them, moving them, causing them to become at leastpartially transparent, etc.), or any other output (visual, auditory,haptic) that can be applied to a notification. At block 606, process 600can display the notification with the notification properties mapped tothe notification type in the mapping accessed at block 604. Process 600can then end.

FIGS. 7A-7C are conceptual diagrams illustrating an example ofdisplaying a notification in minimized and maximized configurationsaccording to wrist rotation trigger events. Referring to FIGS. 7A-7Ctogether, the example begins at 700, where a minimized version of apending notification 704 is attached to a virtual representation of auser's hand and wrist 702. At 730, the artificial reality systemidentifies a rotation of the wrist 702, as illustrated by arrow 732. Thewrist rotation 732 rotates the wrist 702 until the side opposite theminimized version of the pending notification 704 is directed toward theuser's face. The artificial reality system identifies this as a triggerevent, causing the minimized version of the pending notification 704 tobe removed and a maximized version of the pending notification 734 to beshown relative to the part of the wrist directed toward the user's face.The maximized version of the pending notification 734, in this example,includes an icon from the minimized version of the pending notification704 and a text from the pending notification. At 760, the artificialreality system identifies a second rotation of the wrist 702, asillustrated by arrow 762. The wrist rotation 762 rotates the wrist 702 athreshold amount in a direction opposite from the rotation 732. Theartificial reality system identifies this second rotation 762 as asecond trigger event, causing the maximized version of the pendingnotification 704 to be removed from the artificial reality environment.

FIGS. 8A-8D are conceptual diagrams illustrating an example ofdisplaying a notification in minimized and maximized configurationsaccording to user gaze trigger events. Referring to FIGS. 8A-8Dtogether, the example beings at 800 where a minimized version of apending notification 804 is displayed for a user 802 in a corner of theuser's current view. The artificial reality system is tracking a gazedirection 806 of the user 802. At 830, the artificial reality systemidentifies that the tracked gaze 806 is directed at the minimizedversion of the pending notification 804. When the gaze 806 has beendirected at the minimized version of the pending notification 804 for athreshold amount of time (e.g., 1, 2, or 3 seconds), the artificialreality system identifies this as a trigger event. At 860, in responseto the trigger event, the artificial reality system causes the minimizedversion of the pending notification 804 to be replaced with a maximizedversion of the pending notification 862. The maximized version of thepending notification 864, in this example, includes an icon from theminimized version of the pending notification 804 and a text from thepending notification. The artificial reality system continues to trackthe gaze direction 806 as it lingers on the maximized version of thepending notification 864. When the tracked gaze 806 leaves the maximizedversion of the pending notification 864 for a second threshold amount oftime (e.g., 1, 2, or 3 seconds), at 890, the artificial reality systemidentifies this as a second trigger event, causing the maximized versionof the pending notification 804 to be replaced with the originalminimized version of the pending notification 804.
